K&N 57i Series Induction Kits are specifically designed for each different vehicle and will free your car from the size restriction that comes with the factory air box. These economical kits can take a variety of different forms based on vehicle characteristics and available space under the hood. Each kit is designed to provide power throughout the RPM range. The extra surface area of these open-air air filters provide even more airflow at lower restriction than a K&N O/E replacement filter which is always limited to the size of the factory air box. The larger air filter also captures and holds more dirt increasing its service life before a cleaning is required (up to 100,000 miles). The filter is either directly attached to the engine carburetor or throttle body or indirectly through a tube assembly running from the filter to the engine. All adapters are made from high quality materials such as steel, aluminum, silicon or reinforced nylon to ensure long life. 57i Intakes are not legal for use in California and other US States adopting California emission standards.

I recently acquired a brand new BMW 120i cabriolet. Since I live in a city at 2700 foot altitude, the car losses horse power and it becomes almost unpleasant to drive in such conditions. I begun searching with my friends and I thought to remap the ECU, but you all know it could be a little bit risky because you can void your guarantee as well as the RON of our gas is not enough to support new map. Then I decided to go for an intake and filter from K&N. I have to confess I was skeptical about what I saw on the internet, where you can find good and bad experiences. At the end, I took my chances and replaced the air box for the K&N intake system. The result... I was amazed about the sound. The engine's sound seems to be more powerful, but the deal was closed once I get into my car and drove it. The lag of the acceleration almost disappeared and for sure I could feel more power and torque. The feeling of driving such a car is now different and totally pleasant in terms of power, sound and acceleration. Thanks K&N... You gave me back the good feeling of having a BMW.
